3mirrors Shaft Adapter Pulley Stainless Steel 3/4" to 1" Inch Gas Engine Pulley Crank Shaft Sleeve Adapter Predator w/Step Key

Worked like a charm. Fit the motor shaft and the pully. I would recommend buying again

Worked very well and just needed to cut to fit

This allowed my to use a different engine on my Dixie chopper

Works as advertised.

I bought the sleeve and stepped key to adapt a 3/5" output Predator engine to a older shredder/chipper with a 1-inch bore. The sleeve and key both fit perfectly. Although I was a bit concerned that the key is shorter than the original. My concerns were perhaps confirmed when the smaller stepped portion of the key sheared off. To be fair the bolt on the output shaft of the motor broke, but I don't know if it was the key that failed first or the bolt. The motor is a 7 HP predator that is taking the place of a five-horsepower Briggs & Stratton. In case it was the bolt that failed, I am buying another sleeve and key.

Perfect fit couldn’t be any better let me put hubs on my lawn mower so now I have a 5 lug

This is the ticket if you are using a Predator engine as a replacement. I had to shorten mine but the fit was spot on.

For my needs (adapting an older .75" bore pulley onto a newer .625" motor arbor) it was WAY too loose. It might be fine for emergency or short term use, but not for refurbishing a 1940's metal lathe. I ended up ordering one from Grainger that was adequate. Once the lathe is working, I'll just turn a new pulley and throw all the adapters away...
